To all whom t may concern:

Be it known that WILLIAM S. VVLoUeEE, a citizen of thev United States, residing in Rochester, in the county of Stradordand State or' New Hampshire, have invented an improvement in Crimping or Corrugating Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to a crimping orl corrugating machine, which is especially designed and adapted for 'crimping or corrugatingthe lip ofa channeled inner sole.

The invention has for its object to provide a simple, eflicient and inexpensive machine, which i is particularly usefulxfor 'providing the lip of the inner sole with a :corrugation or crimp, which is deeper at the free edge of the lip and diminishes to substantially nothing near the bottomof the lip, whereby an inner sole of substantially non-compressible material may be provided with a lip, which extends substantially atriglit ang-les tothe body portion of the inner sole. fFor this purpose, the machine is provided with cooperating rotatable Vbeveled vcrimping members, having teeth O r crimping edges, which are of greater depth at one surface than at the otherof said members to-orm tapering teeth, so that the work passed between the. intermeshing members may 'be provided with a tapering corrugation or crimp, as will be described. Provision is made for driving the crimping members in unison, and for supporting the 4work while being crimped. Provision is alsomade for compensating Jfor different thicknesses 'of stock, as will be described. The particular features `of the invention will bepoint'ed out in the claims at the end of this specification.

Figure l is a side elevation-of a machine embodying this invention.`Y Fig. 2, a hori- Zontal section on the line 2-2, Fig. l.y Fig. 3, a vertical section o n the line 3.--3,1Fig. 2. Fig. 4, a detail in section of the crimping members shown in Fig. l. Fig. 5, a modiication to be referred to, and Figl, an elevationot a portion of a lip provided with corrugationsor orimpsmaldeiwith the ma chine herein shown. Y

Referring to Figs. l and 4: a, represent two rotatable crimping or corrugatingmembers, by meansofwhich a lip c on a channeled inner sole CZ of substantially'non-compressible material, may be provided with crimps or corrugations l0, see Fig. 6, which are materially deeper at the free edge of the lip o and taperto nothing near the bottom of said lip. Forthis purpose the rotatable crimping member a is,provided with a beveled circumference having teeth '12, which are of greater' depth at one surface and taper or incline to substantially the circumferential edge of theotlier opposite surface, whereby the member t islplrovided on itsperiphery with tapering teeth ofsiib- Sltntially Vno depth` at one surface and of maximumldepth the other: or opposite surface. 1 u ""1 The crimping member is provided with similar teeth which are of greatest depth at .the upper surface, and taperA to notl'iing at the lower surface. i i' The members a, have their teeth intermeshed, with sufficient sgpacerleft-lbetween the outer ,edge of a tooth' on one member `and the bottoiiinwall 15 of ,at'ooth of tlieother member, for the passage of" the lip which is fed between the members a, o landisA vided ,with'crimps orcorrugatins O, see Fig. 6, whicliV are of greatest depth and widthI at the upper orT free edge of the lip, and taper ordiminish to nothing at or near the bottom of the lip, where the latterjoins the body portionof the inner sole.

L In Figl, the members a, ZJ, are shown as arranged in the same plane and are rotated in unison.: To this end, the member 'fr is `fast on a shaft` Q0 having bearingsin'a vertical head Qlfof a` stationaryframework 2Q, and providedlwith a gear 23, which meshes with a gear 24 on a shaft, onwhich the member Z1 is mounted. `The shaft 25 has bearings in a `block 26, `which is mounted to turn on pivots 27, see Fig. 2, carried by the stationary `framework of the machine. The block 26 is yieldingly held up against the head 21 `by springsQQ, whichei'icircle rods 4E30 extended looselythrough the lower endof` the block A26 and secured kto the head 2l `of the framework. AThe springs 29A allow the block 26'to be moved backward en its pivots-27,

to compensate for different thicknesses in ythe lip c passing between the crimping membersra, b. A

The shaft may be driven in any suitable manner, and is shown as provided with a bevel gear 32, which meshes with a bevel gear 33 on amain or driving shaft 34,

v ner sole, while the lip is being crimped by the members a, VZ), and for this purpose, a disk. 4() having a substantially' flat upper surface is loose on a rod 4l, which is extended down through the base 38 and is designed tofbe connected with a treadle, notcshown, bymeansof which the work supporting disk 40 may be lowered away from the crimping members a, b, to place the inner sole in position to have its lip o crimped, and to remove the inner sole from the machine after thelip has been crimped.

The work support or disk 40 is'moved upwardly with the rod 41 by a spring 42, which encircles the rod 4l between a hanger 43 and a disk 44 fast on said rod.V rThe spring 42 acts to press the work or inner sole up against the rotatable member b. Thedownwardlmovement of the work support or disk 40 is limited by a suitable stop, shown as the top of the base 38, and the latter may have erected upon it a post 46 to serve as an auxiliarysupport for theinner sole.

The member may be positioned with relation to themember a to Iadjust the said members for lips of different. thickness, by a threaded rod 50, which extends through the head 21 of the stationary framework, and acts as a Vstop to limit the movement of the block 26 under Vthe influence rof the springs 30.

The lip c is normally flat on the inner sole cl, and provision is made for turning the` same into a position substantially at right angles thereto, so that the lip may be properly presented to the crimping members a, b, and for this purpose I have provided a wire rod 5l, which is fastened as by a screw 52 or otherwise, to a plate 53 attached to the head 2l of the framework, said wire rod having a curved arm 54, which is beveled and has its free end arranged in close proximity to the members a, b, at the point where they intermesh.

In operation, the inner sole d with the lip c in its normal or flat position is placed upon the work support 40 after the latter hasfbeenlowered bythe operator, and when placed thereon so V that one end ofthe lip is in position to be engaged by the turning de- Vofthe lip' is passed between the crimping members a, b, which crimp or corrugate the lip after the manner shown 1n F 1g. 6. After the lip has been crimped, the work support 40 is lowered, to permit the crimped inner sole to be removed and an uncrimped inner sole to be placed on the work support. The crimping members a, b, are shown in Figs. l and 3 as arranged in the same horizontal plane, but it is not desired to limit the inventionin this respect, as they may be arranged in planes substantially at right angles to each other, as represented in Fig. 5, and when so arranged, the lip c is given a greater inclination beyond a position substantially at right angles to the inner sole. When the crimping members a, b, are arranged as shown in Fig. 5, the hub of the member b is made large enough to engage the inner sole to feed the same.

I have herein shown one construction of machine embodying this invention, but it is not desired to limit the invention to the particular construction shown.
